Gambling by itself is ok its only the excess that is where it can be a problem. Uganda is not especially a free democratic country, we cannot say his plan for carrying on his good works but anyone can gamble so long as they only risk what they lawfully earnt we are free to spend in that respect.
however, if the church in Uganda makes sense of what the priest is doing then they really go too far, and the domino effect that will occur will truly be unstoppable, many other priests will become gamblers and close their churches
As for the Uganda episode, let's not be hasty. Though the priest's promotion of gambling raises eyebrows, we're not privy to the entire narrative. He could be funneling proceeds to philanthropy, or perhaps there's another angle. Let's remain open-minded and amass the evidence before passing judgment.
